2.3 Operation – Quick Setup
The DP83561EVM can operate from a single Wide-Vin 5V-36V DC supply connected to the power jack J16
or the header J18. The DP83561-SP is configured for Dual Supply Mode by default. Due to RJ45 orientation
and routing, Mirror Mode is enabled by default. Refer to
for additional information on Mirror Mode
configuration. The DP83561EVM can be quickly configured as follows:
• Ensure shunt removed at J37 header (set PHY for dual supply mode)
• Place shunt at J15 connecting pins 2 and 3.
• Ensure shunt removed at J23 to disconnect VDDA1P8 LDO (not needed in dual supply mode)
• Place shunt at J20 to connect VDDA2P5 LDO
• Place shunt at P2 in the 3.3 V position to connect VDDIO LDO
• Ensure shunts removed on J35 and J36.
• Place shunt at J24 to connect VDD1P1 LDO
• Ensure shunt removed at J21 header
• Place shunt at J31 to enable Mirror Mode (if necessary, refer to
).
